IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 218,109, dated August5, 1879; application filed March 1, 1879.

To all whom it may concern:

Be it known that I, WENDELL V. BRAD- DICK, of North Belle Vernon, in thecounty of Westmoreland and State of Pennsylvania, have invented certainnew and useful Improvements in Cooking-Stoves or Ranges; and 1 do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to cooking-stoves or ranges; and it consists of theparts and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a dissected View of a portion of my stove,showing the relation and arrangement of parts therein indicated. Fig. 2is a perspective view of my device with the top removed, showing itsconstruction. Fig. 3 is a view in longitudinal section of my stove. Fig.4 is a vertical sectional view through line a: m of Fig. 1.

The solid and broken arrows in the drawin gs are intended to representthe direction of draft under different conditions, as will hereinafterappear.

Inasmuch as the construction of stoves is an art so well known, I do notdeem it essential to specify definitely the manner of construction ofeach individual part of my device, but consider it sufficient to combinea description of its operation with such a specification of itsarrangement and construction as follows:

I prefer placing the hot-water tank G on one side of the stove, asindicated in the drawings, and when this and the other parts arearranged as shown in Fig. 1 of the drawings the direction of the draftwill be as follows: Starting from the grate or combustion-chamber itpasses over the top oven-plate, S, thence down the flueS between the endplate, K, and the back ovenplate, L. It is then thrown slantingly acrossthe bottom flue, H, as shown by reference to the bottom flue-plate, A,in Fig. 1. This insures an effectual and even heating of the bottom ofthe oven.

It will be observed that the bottom flue, H, is formed between thebottom of the oven and the bed-plate of the stove, and communicates withthe rear flue, S, which latter is formed between the back end of theoven and the rear end plate of the stove.

From the end of the flue-plate A the draft is toward the flue Gsurrounding the hot-water tank G. When it is desired to heat the waterin said tank, the bottom damper, B, should be opened. This will admitthe major portion of the products of combustion into the indirectsmoke-flue G, in which tank G is placed, from whence the draft willproceed up on the front side of the upright flue plate 0. If it isdesired not to heat the water in the tank G, then the damper B isclosed, and thus the draft and hot air will be cut off from the saidtank G and go up the flue G between the end plate, K, and uprightflueplate 0. The upright flue-plate G is placed at or near the middleportion of the stove-pipe collar or exitflue; and this constitutes animportant feature of my invention, for the reason that when water is tobe heated in the tankG, by opening the damper B, as before specified, Iwill get nearly all of the products of combustion on the front side ofthe upright flue plate 0, directly adjacent to the hot'water tank G, asthis is the most direct passage of escape when the damper B is open.

It will be observed that the hot-water tank G is incased by back plate,F, division plate D, small front plate, E, and upright flue-plate 0,thus making a smoke-flue, G, which surrounds the water-tank on allsides.

The division-plate D does not go down entirely to the bottom of thestove, as will be seen in the drawings.

The broken arrows indicate the direction of the draft beneath saidplate; and it will be observed that the lower portion of this plate,which is included between the upright flueplate 0 and the end plate, K,is cut so as to make the passage which leads into flue G of greatervertical dimension than the passage which leads into flue Gr.

My reason for this construction is to provide a larger opening for theproducts of combustion to pass out in free draft when it is not desiredto heat the tank, for at such times the damper B is closed, thusshutting the opening under the divisionplate D, which compels the draftto go the other way. The hotwater tank G does not extend quite to thebottom edge of the division-plate D.

My reason for having it so is to provide a protection for said tank bynot permitting the flames to strike it, as they will strike thedivision-plate D first, thus breaking the flames without any materialloss of heat. This provision also enables me to get all my heat on theup-draft, which, so far as I am aware, is not obtained in the hot-watertanks of other stoves. This is an advantagein my estimation, as moreheat can be had on an tip-draft than on a down-draft. Not only this, butthe water in the tanks of other stoves, so far as my knowledge goes,absorbs a great amount of the heat before it gets around the oven, thusunnecessarilyintertering with baking-an objection overcome by my device,as the heat in my stove travels around the oven before reaching thewater-tank and at the same time the water-tank is sufiiciently away fromthe flames to escape their injurious action, yet at the same timereceive sufiicicnt heat.

I have increased the baking capacity and function of my device aboveordinary stoves that have two independent oven-doors, which admit agreat amount of cold air to the oven, which is only heated from thefront, top, back, and bottom.

A range or stove having but one oven-door is an improvement over the oldmultiple-door stove; but still they are not heated from any more sidesthan the old stove, unless by a due running up the back.

My stove or range has but one oven-door, and is heated from the front,the top, the end, bottom, and back, making in all five sides.

The small plate A shuts the opening between the division-plate l) andthe bottom flue-plate, A. This provision is made to compel the productsof combustion to come upon the side of the flue-plate indicated by thearrows; otherwise they would pass down upon the other side of the bottomflue-plate, A, and go directly up and out through the exit-flue.

B is the direct-draft damper, and when a direct draft is wanted thisdamper should be opened. The solid-line arrows in Fig. 2 of thedrawings, however, will show the direction of draft when the damper B isclosed.

The peculiar form of oven-door shown in the drawings does not constituteany part of the invention claimed in this patent; and I reserve theright to hereafter make a separate application for patent thereon.

What I claim is- 1. The combination, with the rear flue, S, and thebottom flue, H, provided with the diagonal plate A, of the verticalreturn-flue G and the flue G, in which the water-tank is iocatcd,substantially as set forth.

2. The combination, with the rear vertical flue, S, provided with thehorizontal plate A, and the bottom flue, H, provided with the diagonalplate A, of the vertical return-flue C and the fiue G, in which thewater-tank is localed, substantially as set forth.

3. The combination, with the rear flue, S, and the bottom line, H,provided with the diagonal plate A, of the due G, in which thewater-tank is located, and which is provided at its lower portion withthe damper regulating its communication with said bottom flue,substantially as set forth.

4. The combination, with the bottom flue, H, and the line G, in whichthe water-tank is located, of the vertical flue 0, whose lower portioncommunicates with the bottom flue in indirect draft, and whose upperportion has damper communication in direct draft with the top flue,substantially as set forth.

5. The combination, with the bottom flue, H, of the flue G, in which thewater-tank is located, and the line C, said flues G and 0 openingdirectly into the final exit-flue of the stove or range, substantiallyas set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
